DETAILED DESCRIPTION

[0036] Example embodiments will now be described more fully with reference to the accompanying drawings. However, the example embodiments can be implemented in many forms and should not be construed as limited to the embodiments set forth herein; rather, these embodiments are provided to make this disclosure more comprehensive and complete and to fully convey the concepts of the example embodiments to those skilled in the art. Identical reference numerals in the figures denote identical or similar structures, and thus repeated descriptions thereof will be omitted.

[0037] The words expressing positions and directions described in this utility model are all explained with reference to the accompanying drawings as examples, but they can be changed as needed, and all such changes are included in the protection scope of this utility model.

[0038] like Figure 1 As shown, the utility model provides a jacking device, including a base 6 and a driving member 1, a sliding block 2, an inclined wedge 3, a support plate 4 and a jacking member 5 directly or indirectly mounted on the base 6.

[0039] The driving member 1 can be connected to the sliding block 2 so that the driving member 1 can drive the sliding block 2 to move along the first direction. The driving direction of the driving member 1 can be parallel to the first direction, and the driving member 1 can directly drive the sliding block 2 to move along the first direction; or, referring to Figure 1 and Figure 2 , the driving member 1 can be connected to a transmission assembly 11, the driving member 1 can provide a rotational driving force and act on the transmission assembly 11, the transmission assembly 11 is used to convert the rotational driving force of the driving member 1 into a linear driving force along a first direction, so that the driving member 1 and the transmission assembly 11 can together constitute a linear motion module. The transmission assembly 11 is connected to the sliding block 2, and the transmission assembly 11 drives the sliding block 2 to move along the first direction through the rotational driving force provided by the driving member 1. In this embodiment, the driving member 1 can provide a rotational driving force, the driving member 1 can specifically be a servo motor, and the transmission assembly 11 can specifically be a screw structure. Among them, the driving member 1 and the transmission assembly 11 can be fixedly mounted on the base 6, for example, fixedly mounted on the base 6 by fasteners such as screws.

[0040] Reference Figure 2The sliding block 2 can be connected to the bevel wedge 3 and can drive the bevel wedge 3 to move in the first direction. To guide the movement of the bevel wedge 3, a slide rail 61 and a slider 62 can also be provided on the base 6. The slide rail 61 can be fixed to the base 6 by fasteners such as screws, and the extension direction of the slide rail 61 is parallel to the first direction. The slider 62 slides with the slide rail 61 so that the slider 62 can be guided by the slide rail 61 and slide in the first direction. At the same time, the slider 62 can be connected to the bevel wedge 3 and can move synchronously with the bevel wedge 3. In this case, the movement of the bevel wedge 3 and the slider 62 can be guided by the slide rail 61 that slides with the slider 62 and maintains movement in the first direction. There can be two sliders 62 and two slide rails 61 respectively. Each slider 62 and the corresponding first slide rail 61 form a sliding matching group. The two sliding matching groups are distributed on opposite sides of the sliding block 2 and are used together to guide the movement of the sliding block 2 and the bevel wedge 3, thereby improving the stability of the movement of the bevel wedge 3.

[0041] The connection between the sliding block 2 and the wedge 3 may include a direct connection or an indirect connection. For example, the sliding block 2 may be directly fixedly connected to the wedge 3 by screws or other fasteners, and the wedge 3 is fixed to the slider 62 by screws or other fasteners, so that the sliding block 2 can drive the wedge 3 and the slider 62 to move synchronously. Alternatively, the sliding block 2 may be fixedly connected to the slider 62 by screws or other fasteners, and the wedge 3 is fixed to the slider 62 by screws or other fasteners, and the sliding block 2 is indirectly connected to the wedge 3 through the slider 62 and can drive the slider 62 and the wedge 3 to move synchronously. Alternatively, refer to Figure 2 The sliding block 2 can be fixedly connected to the connecting block 21 via screws or other fasteners. The angled wedge 3 and the slider 62 are also fixedly connected to the connecting block 21 via screws or other fasteners. The angled wedge 3 and the slider 62 can be located on opposite sides of the connecting block 21. When the sliding block 2 moves, the sliding block 2 is indirectly connected to the angled wedge 3 and the slider 62 via the connecting block 21, and can drive the slider 62 and the angled wedge 3 to move synchronously.

[0042] The support plate 4 and the angled wedge 3 can be in an oblique sliding engagement. The direction of the oblique sliding between the support plate 4 and the angled wedge 3 is inclined relative to the first direction and the second direction, and intersects with the first direction and the second direction, respectively. This allows the support plate 4 to move in the second direction when the angled wedge 3 moves in the first direction and drives the support plate 4 to engage obliquely with the angled wedge 3. The first direction is perpendicular to the second direction, and the first direction can be specifically a horizontal direction, while the second direction can be specifically a vertical direction.

[0043] By adopting a structure in which the support plate 4 and the inclined wedge 3 slide in an oblique manner, the driving structure, that is, the driving member 1 and the transmission assembly 11, can directly drive the support plate 4 without the need to drive the support plate 4 along the second direction, and the length direction of the driving member 1 and the transmission assembly 11 in the present application can be parallel or approximately parallel to the first direction. Therefore, the driving member 1 and the transmission assembly 11 do not need to occupy a higher height in the second direction, thereby reducing the volume of the jacking device to provide a small-sized jacking device and reduce the volume of the annealing device using the jacking device.

[0044] Reference Figure 5 and Figure 6 To achieve the oblique sliding fit between the support plate 4 and the cam 3, the support plate 4 may be connected to a follower 41. One end of the follower 41 is fixedly connected to the support plate 4, for example, by being locked to the support plate 4 via a nut. The other end of the follower 41 may be located on the side of the support plate 4 facing the cam 3 and configured to fit with the cam 3. The cam 3 may be provided with an oblique groove 31, the extension direction of which is the same as the direction of the oblique sliding between the support plate 4 and the cam 3. When the follower 41 fits with the cam 3, the portion of the follower 41 located on the side of the support plate 4 facing the cam 3 may be received within the oblique groove 31, allowing the follower 41 to slide along the extension direction of the oblique groove 31. This, in turn, allows the support plate 4 fixedly connected to the follower 41 to slide relative to the cam 3 along the extension direction of the oblique groove 31. Furthermore, the support plate 4, which is fixedly connected to the follower 41, may then convert the movement of the cam 3 in a first direction into the movement of the support plate 4 in a second direction through the oblique sliding fit structure.

[0045] To improve the stability of the support plate 4 during movement, multiple angled wedges 3 can be provided, and the support plate 4 is connected to multiple followers 41. Each follower 41 cooperates with a angled wedge 3 to enable the support plate 4 to slide obliquely with the angled wedge 3. When the support plate 4 moves in the second direction, the support plate 4 can obliquely cooperate with the multiple angled wedges 3. The multiple angled wedges 3 can jointly drive the support plate 4 to move and simultaneously guide the support plate 4 through the oblique sliding cooperation with the support plate 4, thereby effectively improving the stability of the support plate 4 during movement.

[0046] Among them, reference Figure 3, multiple inclined wedges 3 can be distributed on opposite sides of the sliding block 2. The inclined wedge 3 located on one side of the sliding block 2 can be connected to the slider 62 located on the same side of the sliding block 2, and the inclined wedge 3 located on the other side of the sliding block 2 can be connected to the slider 62 located on the other side of the sliding block 2, so that the matching structure of one slider 62 and the slide rail 61 can simultaneously guide one or more inclined wedges 3 located on one side of the sliding block 2. Only a part of the multiple inclined wedges 3 can be connected to the sliding block 2 and driven by the sliding block 2. Specifically, the multiple inclined wedges 3 include at least one active inclined wedge 32 and at least one driven inclined wedge 33. The active inclined wedge 32 is connected to the sliding block 2 and driven by the sliding block 2, and the driven inclined wedge 33 can be connected to the active inclined wedge 32, so that the driven inclined wedge 33 can move under the drive of the active inclined wedge 32. By dividing the multiple cam wedges 3 into active cam wedges 32 and passive cam wedges 33, the sliding block 2 does not need to be connected to all of the cam wedges 3 to drive the movement of the multiple cam wedges 3. This simplifies the connection structure between the sliding block 2 and the cam wedges 3, and simplifies the connection steps between the sliding block 2 and the cam wedges 3. Specifically, when the cam wedge 3 is a passive cam wedge 33, the passive cam wedge 33 is connected to a corresponding slider 62 via a connecting block 21 and is not connected to the sliding block 2.

[0047] The active cam 32 and the driven cam 33 are connected via a connecting rod assembly 34, allowing the active cam 32 to drive the driven cam 33 to move. The connecting rod assembly 34 may include a connecting rod 341 and a floating joint 342 disposed at the end of the connecting rod 341. The connecting rod 341 may extend in a direction parallel to the first direction. By utilizing the structure of the connecting rod 341 and the floating joint 342 to achieve the connection between the active cam 32 and the driven cam 33, the active cam 32 and the driven cam 33 connected thereto can maintain contact with the follower 41, thereby improving the driving stability of the active cam 32 and the driven cam 33 connected thereto on the support plate 4. Among them, the end of the connecting rod 341 away from the floating joint 342 can be connected to the active wedge 32, and the end of the connecting rod 341 with the floating joint 342 can be connected to the driven wedge 33 through the floating joint 342; or, the end of the connecting rod 341 away from the floating joint 342 can be connected to the driven wedge 33, and the end of the connecting rod 341 with the floating joint 342 can be connected to the active wedge 32 through the floating joint 342.

[0048] Multiple active cam wedges 32 can be provided, with the multiple active cam wedges 32 distributed on opposite sides of the sliding block 2. Multiple driven cam wedges 33 can be provided, with the multiple driven cam wedges 33 distributed on opposite sides of the sliding block 2. The active cam wedges 32 and driven cam wedges 33 located on the same side of the sliding block 2 are connected by a connecting rod assembly 34, and the active cam wedges 32 and driven cam wedges 33 located on the same side of the sliding block 2 are connected to the same slider 62. The active cam wedges 32 and driven cam wedges 33 located on the other side of the sliding block 2 are connected by a connecting rod assembly 34, and the active cam wedges 32 and driven cam wedges 33 located on the other side of the sliding block 2 are connected to another slider 62. Specifically, two active cam wedges 32 and two driven cam wedges 33 can be provided, respectively, with two active cam wedges 32 distributed on opposite sides of the sliding block 2 and two driven cam wedges 33 distributed on opposite sides of the sliding block 2, and each active cam wedge 32 is connected to a driven cam wedge 33 on the same side via a connecting rod assembly 34.

[0049] Reference Figure 4 The support plate 4 may specifically include a first plate body 42, a second plate body 43, and a connecting plate 44 connecting the first plate body 42 and the second plate body 43. The first plate body 42 and the second plate body 43 are distributed on opposite sides of the sliding block 2, for example, the first plate body 42 is located on the first side of the sliding block 2, and the second plate body 43 is located on the second side of the sliding block 2. The first plate body 42 and the second plate body 43 may be connected to followers 41, respectively. The first plate body 42 may be connected to the active cam 32 and the driven cam 33 located on the first side of the sliding block 2 through the follower 41, and the second plate body 43 may be connected to the active cam 32 and the driven cam 33 located on the second side of the sliding block 2 through the follower 41. One end of the connecting plate 44 is fixedly connected to the first plate body 42, and the other end is fixedly connected to the second plate body 43, so that the first plate body 42, the second plate body 43 and the connecting plate 44 can together form a fixed structure.

[0050] When the support plate 4 is driven by the wedge 3 to move, to prevent the support plate 4 from following the wedge 3 and moving in the first direction, a guide post 63 extending in the second direction may be provided on the base 6. The guide post 63 passes through the support plate 4 and is used to guide the support plate 4 in the second direction. A plurality of guide posts 63 may be provided, with some of the guide posts 63 connected to the first plate 42 of the support plate 4 and some of the guide posts 63 connected to the second plate 43 of the support plate 4. The plurality of guide posts 63 collectively guide the support plate 4, ensuring smooth movement of the support plate 4 in the second direction.

[0051] The lifting member 5 is used to lift the target part. The lifting member 5 is connected to the support plate 4 and can move along the second direction with the support plate 4. For example, the support plate 4 is provided with a socket, and one end of the lifting member 5 is inserted into the socket of the support plate 4, so that the support plate 4 can drive the lifting member 5 to move synchronously along the second direction, thereby enabling the lifting member 5 to lift the target component along the second direction. Among them, there can be multiple lifting members 5, a part of the lifting members 5 is arranged on the first plate body 42 of the support plate 4, and a part of the lifting members 5 is arranged on the second plate body 43 of the support plate 4. Multiple lifting members 5 are used together to lift the target component. The target component is a component that needs to move up and down along the second direction, for example, the target component is a perovskite film or a substrate carrying a perovskite film. Among them, the lifting member 5 can specifically be a pin.

[0052] It should be noted that the movement in the first direction is not limited to the positive direction of the first direction, but may also include movement in the opposite direction of the first direction. The movement in the second direction is not limited to the positive direction of the second direction, but may also include movement in the opposite direction of the second direction.

[0053] The present invention also provides an annealing device comprising the aforementioned lifting device and an annealing chamber. A target component, such as a perovskite film, can be placed in the annealing chamber. A lifting member 5 of the lifting device can penetrate into the annealing chamber and support the perovskite film, allowing the perovskite film to be lifted by the lifting device.
